rstest

A fast, pytest-compatible test runner. Rust orchestration, your tests unchanged: same plugins, same fixtures, same outcomes — parallel by design, with built-in suite diagnostics (--doctor).

pip install rstest
rstest

Parallel by default (-n auto). Tests that can't run in parallel can be marked @pytest.mark.serial (they run exclusively, after the parallel phase), order-dependent suites can use --dist loadfile, and rstest -n 0 gives a single pytest session with byte-exact pytest semantics.

The compat contract: at -n 0, outcomes are byte-exact. In parallel modes, outcomes are preserved for parallel-safe tests; tests with hidden time/ordering/shared-state assumptions can flake under high concurrency — exactly as under pytest-xdist. rstest --doctor and lower -n values help find and contain them; @pytest.mark.serial is the escape hatch.

Highlights:

Drop-in: forwards the pytest flag surface; runs conftest, fixtures, parametrize, marks, and pytest plugins (pytest-django, pytest-asyncio, hypothesis, ...) through a vendored pytest core.
Parallel by design: test-granular work distribution with duration-aware scheduling; @pytest.mark.serial and --dist loadfile safety rails; crashed workers respawn without losing your run.
rstest --doctor: wait-bound tests, parallel-floor analysis, fixture hotspots, slowest files.
rstest --watch: instant reruns on save; changed test files rerun alone, source changes rerun only the tests the import graph says are affected.
